2. 1. Carbon Fibres from Kraft Lignin

   Author : Ida Norberg; Monica Ek; Elisabeth Sjöholm; Göran Gellerstedt; Falk Liebner; KTH; []
   Keywords : ;

   Abstract : Kraft lignin has a high potential for use in more valuable applications than its current use as fuel in pulp mills and integrated pulp and paper mills. The possibility of using kraft lignin, a green material with a carbon content of more than 60 %, for the manufacturing of carbon fibres was investigated in this thesis. READ MORE

   Abstract : It is in the nature of the human species to find solutions of complex technical problems and always strive for improvements. The development of new materials is not an exception. One of the many man-made materials is carbon fibre (CF). READ MORE

5. 3. Valorization of Kraft Lignin by Fractionation and Chemical Modifications for Different Applications

   Author : Selda Aminzadeh; Mikael Lindström; Hasan Jameel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin Valorization- LignoBoost Lignin-Clean Flow Black Lignin- Characterization-Chemical modifications-Fractionation-applications; Chemical Engineering; Kemiteknik;

   Abstract : AbstractLignin is one of the most abundant biopolymers. Approximately 70 million tons of technical lignin is generated annually, but only little is used for products other than energy. The complexity of lignin hinders full utilization in high-value products and materials. READ MORE
